</span> * Creates a Bar Chart. A Bar Chart is a useful visualization technique to display quantitative information for
 * different categories that can show some progression (or regression) in the dataset. As with all other series, the Bar
 * Series must be appended in the *series* Chart array configuration. See the Chart documentation for more information.
 * A typical configuration object for the bar series could be:
 *
 * {@img Ext.chart.series.Bar/Ext.chart.series.Bar.png Ext.chart.series.Bar chart series}
 *
 *     var store = Ext.create('Ext.data.JsonStore', {
 *         fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
 *         data: [
 *             {'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
 *             {'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
 *             {'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
 *             {'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
 *             {'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}
 *         ]
 *     });
 *     
 *     Ext.create('Ext.chart.Chart', {
 *         renderTo: Ext.getBody(),
 *         width: 500,
 *         height: 300,

 *             },

 *             highlight: true,
 *             tips: {
 *               trackMouse: true,
 *               width: 140,
 *               height: 28,
 *               renderer: function(storeItem, item) {
 *                 this.setTitle(storeItem.get('name') + ': ' + storeItem.get('data1') + ' views');
 *               }
 *             },
 *             label: {
 *               display: 'insideEnd',
 *                 field: 'data1',
 *                 renderer: Ext.util.Format.numberRenderer('0'),
 *                 orientation: 'horizontal',
 *                 color: '#333',
 *                 'text-anchor': 'middle'
 *             },
 *             xField: 'name',
 *             yField: ['data1']
 *         }]
 *     });
 *
 * In this configuration we set `bar` as the series type, bind the values of the bar to the bottom axis and set the
 * xField or category field to the `name` parameter of the store. We also set `highlight` to true which enables smooth
 * animations when bars are hovered. We also set some configuration for the bar labels to be displayed inside the bar,
 * to display the information found in the `data1` property of each element store, to render a formated text with the
 * `Ext.util.Format` we pass in, to have an `horizontal` orientation (as opposed to a vertical one) and we also set
 * other styles like `color`, `text-anchor`, etc.
